A Model Context Protocol server that bridges AI models with WinDbg for crash dump analysis, user-mode remote debugging, and kernel debugging.

Overview

This server drives the Windows debuggers - CDB for user mode (dumps and -remote) and KD for kernel targets (-k) - so you can debug in natural language: "Show me the call stack and explain this access violation" or "Open a kernel session and tell me which driver bugchecked."

It is not a magical auto-fix. It is a Python wrapper around cdb.exe / kd.exe that lets an LLM run real debugger commands and reason about the output.

Features

  • Crash dump analysis - open a .dmp/.mdmp/.hdmp and get automated triage (!analyze -v, stacks, modules, threads) in a single call.
  • User-mode remote debugging - attach to a live cdb/WinDbg debug server (-remote) over TCP, a named pipe, or COM, and break in on demand.
  • Kernel debugging - attach to a kernel target (-k, driven by kd.exe) over KDNET, a named pipe, or serial; the server waits for the target and breaks in for you.
  • Run any WinDbg/KD command - drive an open session with arbitrary commands (kb, !process 0 0, !heap, lm, ...) de

Questions

What is the Windbg Analyzer MCP server?

Model Context Protocol for WinDbg.

What tools does Windbg Analyzer expose?

10 in total: 7 read-only, 3 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Windbg Analyzer safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Windbg Analyzer need?

No credential environment variables were found in its source, so it appears to need none.

How does Windbg Analyzer run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on PyPI as mcp-windbg.

How current is this page?

The grade is for one exact copy of the source (e7f795e5326c), read on 2026-09-24. The repository is watched and re-audited when it changes.
